COMPOSITION OF MATTER.

Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed July 15, 1904. Serial No. 216,767.

To all whom it may concern..-

Be it known that I, DAVID LIoHTENsTErN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Composition of Matter,of Which the following is a specification.

My invention relates to a composition of matter embodying suchingredients as to form an adhesive substance possessing properties thatmake sure the firm union of two or more textile fabrics, leather, or awoven fabric and leather, whether of the same or different colors. Thiscomposition consists of the following ingredients in about theproportion stated, to Wit: French glue, one-half pound shellac, twoounces; a solvent such as alcohol, one ounce; water, one gallon starch,one-half pound; glycerin, one ounce; ammonia, one-half ounce; alum, oneounce. For the purpose of giving any particular color or tint to thecomposition any suitable coloringmatter and in any desired quantity maybe used; but the coloring-matter is not essential to the effectivenessof the composition. The most essential of'these ingredients are Frenchglue, shellac, an alcoholic solvent, starch, and water; but theingredients glycerin, ammonia, and alum each contributes more or less tothe perfection of the composition. This adhesive substance may beprepared by lacing the French glue, shellac, and alcoolic solvent in acontainer overnight or until the solids are thoroughly dissolved. The

starch should be mixed with water for about two hours. Then these twomixtures and the glycerin, ammonia, alum, and coloringmatter, if any isdesired, should be assembled in a suitable vessel for commingling byagitation or otherwise and the application of heat during or after suchoperation. It has been found that agitation in the presence of heatimproves the com osition. One way to apply heat is to intro uce steam ator near the bottom of the vessel containing the mixture and subject itto the action of live steam for about five minutes.

One manner of applying my improved adhesive substance is to apply thesame while in a heated condition to the woven fabric, leather, or clothand leather, drawn taut or stretched, the substance being a plied toadjacent sides of the material and both pieces pressed to form one pieceof material before the substance loses its heat, or the adhesivesubstance may be applied to one surface of the material and permitted tocool, and at any time thereafter such treated surface and one surface ofcloth previously moistened may be brought together, heat applied, andboth pieces pressed together to become in appearance a single piece.-

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The hereindescribed composition of matter consisting of French glue,shellac, a solvent, starch and water, substantially as and for thepurpose specified.

2. A composition of matter consisting of French glue, shellac, analcoholic solvent, starch, water, and alum, substantially as specified.

3. As a new composition of matter the mixture containing French glue,shellac, a solvent, starch, water, alum, and ammonia, substantially asspecified.

4. The hereindescribed composition of matter, consisting of French glue,shellac, a solvent, starch, Water, alum, ammonia, and glycerin,substantially as specified.

5. As a new composition of matter the mixture containing French glue,shellac, alcohol, starch, water, alum, ammonia, and glycerin,substantially as specified.

6.The herein-described composition of matter consisting of French glue,shellac, alcohol, starch, water, alum, ammonia, glycerin, andcoloring-matter, substantially as specified.

7. The herein-described composition of matter consisting of French glue,shellac, an alcoholic solvent, starch, and Water commingled in thepresence of heat, substantially as specified.

8. The hereindescribed composition of matter consisting of French glue,shellac, an alcoholic solvent, starch, and water commingled in thepresence of steam, substantially as specified.

9. As a new composition of matter the mixture containing French glue,shellac, alcohol, starch, and water agitated and commingled in thepresence of live steam, substantially as specified.

10. The herein-described composition of matter consisting of Frenchglue, shellac, an

alcoholic solvent, starch, Water, and glycerin commingled in thepresence and by the action of steam, substantially as specified.

11. The herein-described composition of matter consisting of Frenchglue, shellac, alcohol, starch, Water, glycerin, and ammonia agitatedand commingled in the presence of heat, substantially as specified.

12. The herein-described composition of matter consisting of Frenchglue, shellac, alcohol, starch, Water, glycerin, ammonia, and alumcommingled in the presence of heat, substantially as specified.

13. The herein-described composition of matter consisting of Frenchglue, shellac, alcohol, starch, Water, glycerin, ammonia, alum, andcoloring-matter commingled in Fhei presence of heat, substantially asspeci- 1e 14. As a new composition of matter the mixture consisting ofFrench glue, shellac, an alcoholic solvent,'starch, Water, and coloringmatter substantially as and for the purpose specified.

15. A composition of matter consisting of French glue, shellac, analcoholic solvent, starch, Water, and glycerin, substantially asspecified.

16. A composition of matter consisting of French glue, shellac, analcoholic solvent,

starch, Water, and ammonia, substantially as specified.

17. A composition of matter consisting of French glue, shellac, analcoholic solvent, starch, Water, alum, and coloring-matter,substantially as specified.

18. A composition of matter consisting of French glue, shellac, analcoholic solvent, starch, Water, glycerin, and coloring-matter,substantially as specified.

19. A composition of matterconsisting of French glue, shellac, analcoholic solvent, starch, Water, ammonia, and coloring-matter,substantially as specified.

20. A composition of matter consisting of French glue, shellac, alcohol,starch, Water, and coloring-matter agitated and commingled in thepresence of steam, substantially 45 as specified.

In testimony whereof I have signed my name to this specification inpresence of two subscribing Witnesses.
